ISPOR has recently published 3 more in its long series of good research practice reports. They are all published in Value in Health and relate to Conjoint Analysis in Health, Interpreting Indirect Treatment Comparison Studies for Decision-making and Conducting Indirect Treatment Comparison and Network Meta-Analysis Studies.
Whilst the standing of guidelines produced by self-selected panels is always open to question, it is likely that these reports will be influential in defining standard practice within the pharmacoeconomic research community. Being published in an academic journal, they do however, have the advantage of being open to public comment. I’m sure VIH and its Editorial Board (including Alan Brennan) would be pleased to hear them.
